4/7/2006: An off-duty Chicago officer who happened to be in a bar assisted the owner in getting Kenneth Elrod to at closing time. A while later, a white Ford Ranger containing Elrod and Demetri Centera pulled up alongside the officer's car at an intersection. Both men aimed guns at the officer; both men were shot and died at the scene. http://articles.chicagotribune.com/2006-04-08/news/0604080145_1_off-duty-police-officials-police-spokeswoman-monique-bond
